Abstract
An electrostatographic printer includes a development housing for supplying developer to an image receptor, and a replenisher in communication with the development housing. In a basic state, a regular supply of developer having a first predetermined TC is supplied. In a special state, a special supply of developer having a second predetermined TC is supplied. In response to determining the printer should be in the special state, the special supply of developer is requested to be installed in the printer, such as through Internet ordering to a vendor. The vendor can also “custom-blend” a developer formulation based on transmitted machine conditions.
